I have installed a third party webmail solution in /var/www/<directory> My question is how can I integrate this into Plesk so my clients can select it as their webmail option. I can only add a URL into the "Register Additional Webmail" page. I'd rather not remove atmail or horde from the server as some clients are currently happy with these. Seems a bit odd to leave this functionality out at this level... Anyone know any workarounds? Any help and advice much appreciated!
